IMPROVEMENT IN LEATHER BELTING.

Specification forming part of Letters Patent N o. 219,697, dated September 16, 1879; application filed Apri] 23, 1879.

To all whom it may concern:

Be it known that we, FRANK H. UNDER- woon, JAMES E. UNDERWooD, aud G. FRANK of Tolland, in the county of Tolland and State of Connecticut, have invented eertain new and useful Improvements pertaining to Leather Belting, of which the. following isl a specification, reference being had to theaccompanying drawing, which shows a piece of beltin g constructed according to ourinvention, with the Hesh-split started apart at the corner.

The object of this invention is the produc- `tion of a at belt of leather for communicating power from pulley to pulley, much cheapened in cost to the consumer, and much improved in quality as compared with the ordinary belt composed of the entire thickness of the hide.

For many commercial purposes leatherbeef -hidesniay be, and is, split into two layers, that layer bearing the common outer surface being known as the grain-split, andtheinner'layer as the tlesh-split, the latter of which has little commercial value as compared with the whole hide or with the grainsplit. For instance, `hides of grown beef vcreatures are thus split, andthe grain-split used for the manufacture of sewing-machine belts, patent-leather, Ste.

The present market value of the whole hide' is about thirty cents per pound, while the value of the flesh-split is about onefourth as much.

By the aid and exercise of this our present/ invention we are able to convert these comparatively worthless liesh-splits into a powerbelt intrinsically worth as much, or even more, than if the belt had been iliade of a hide of integral and entire thickness.

Our `method is to take two of these fleshsplits, (denoted in the drawing by the letters brought or one not rising Vto face,

,brought together face to face, -or the esh sides-that is, the sides originally nearest the original inner surface-brought together face 'to face, or the' grain sides and the tlesh sides together lface to face, in either way making a belt'of superior strength and durability.

We prefer sewing the splits together for the sake of pliability, and prefer a sunken stitch, above the surface of the leather, to prevent wear of the thread.

.We also prefer putting the grain sides face because it brings the esh sides to the surfaces. They are denser and stronger than the grain sides, wear longer on the'pulleys, and hug them closer.

When the sides are thus brought like and like together',

the belt runs truer than a 'belt of one entire and integral thickness, and betf ter than if a grain side faced a tiesh side.

Actual trial shows that a belt thus made of two of these flesh-splits is stronger and more elastic than au integral belt of the ordinary sort of equalthickness.

We claim as our inventionl. As a new article of manufacture, a powerbelt composed of iesh-splits united together, substantially as shown and described.

2. As an improved article of manufacture, a power-belt composed of iesh-split's united together wi th like sides faced against each other, substantially as shown and described. FRANK H. UNDERWOOD. JAMES E. UNDERWOCD. G. FRANK UHLER. Witnesses:
